laptop Toshiba L775D won't boot

I remember after I went to some Chinese websites, the speed of my laptop suddenly became slower and slower.  One day, my four-year old laptop won't boot at all and came up a message saying something wrong with the Hard Drive, which never being dropped or whatever misused.  Someone formatted the whole computer and it could boot for two days, and then again back to something wrong with the Hard Drive.  Can some expert tell me what wrong with my laptop and teach me how to fix it?  Thanks.


Currently, my kid used Linux (?) thumb drive to boot the laptop, but it is NOT convenient at all.  .

• 显然硬盘已经寿终正寝。格式化后硬盘的坏道被屏蔽，暂时可用，但两天后硬盘又出现了新坏道。 -加州老李- ♂ (99 bytes) () 11/06/2014 postreply 08:02:29
